Find the slope ( rise/run)
Answer:
[tex]\huge\boxed{-\frac{1}{3}}[/tex]
Step-by-step explanation:
In order to find the slope of a line, we need to find the rise over the run.
Basically - the change in y divided by the change in x.
[tex]\frac{\Delta x}{\Delta y}[/tex]
We can compare the two points and find both.
We go from (0, 2) to (3, 1).
From 0 to 3 (x) is 3 units.
From 2 to 1 (y) is -1 units.
Therefore we can divide the x by the y.
[tex]\frac{-1}{3}[/tex]
[tex]-\frac{1}{3}[/tex]
Hope this helped!

There are two gardens, garden A and garden B are shown in the image below.
Determine if statement 2 is true or false and explain why the statement was true or false
Answer:
FalseStep-by-step explanation:
Perimeter of garden A is
P = 2(w + l) = 2( 2x - 3 + 5(2x - 3)) = 24x - 36Perimeter of garden B is
5x + 5 + 4x + 2 + 8x - 8 = 17x - 1Sum of perimeters:
24x - 36 + 17x - 1 = 41x - 37The statement 2 is FALSE as number we got is different from the one in the statement
Answer:
Falsethe equation required to fence both garden do not match the perimeter given on statement 2.41x - 37 ≠ 41x + 35Step-by-step explanation:
garden A
Width (W) = 2x - 3
Length (L) = 5(W)
= 5 (2x - 3)
= 10x - 15
Perimeter A = 2L + 2W (perimeter of a rectangular garden)
= 2(10x - 15) + 2(2x - 3)
= 20x - 30 + 4x - 6
= 24x - 36
garden B
side 1 = 5x + 5
side 2 = 4x + 2
side 3 = 8x - 8
Perimeter B = sides (1 + 2 + 3)
= 5x+5 + 4x+2 + 8x-8
= 5x + 4x + 8x + 5 + 2 - 8
= 17x - 1
Garden A + garden B = statement 2
24x - 36 + 17x - 1
24x + 17x - 36 - 1
41x - 37
therefore, the statement 2 is false. as the equation required to fence both garden do not match the perimeter given on statement 2.
41x - 37 ≠ 41x + 35What’s the median of 1,1,7,3,2,2,3,5

Is the expression 54 divided -6 undefined? If not, find the quotient.
9514 1404 393
Answer:
54/(-6) = -9
Step-by-step explanation:
From your knowledge of multiplication tables, you know that ...
6·9 = 54

Enter an equation in point-slope form for the line.
Slope is 3 and (-8,-1) is on the line.
The equation of the line in point slope form is:
PLEASE HELP!!!
Answer:
y + 1 = 3(x + 8)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 3 and (a, b) = (- 8, - 1) , thus
y - (- 1) = 3(x - (- 8)), that is
y + 1 = 3(x + 8)

find the value of 3/27
Answer:
The cubed root of a number is the number that, when multiplied by itself three times (number x number x number), gives the original number. For example, the cubed root of 27 is 3, as 3 x 3 x 3 = 27. The cubed root of 125 is 5, as 5 x 5 x 5 = 125. Unlike the square root, the cubed root is always positive
Step-by-step explanation:
Here is a picture that shows one side of a child's wooden block with a semicircle cut out at the bottom. What is the area of the wooden block? *HINT (subtract the semi-circle from the rectangle)* The face of an arch-shaped block. The horizontal side of the block is labeled 9 centimeters and the vertical side of the block is labeled 4.5 centimeters. A semi circle with diameter labeled 5 centimeters is removed from the block.
Answer:
30.7 cm² (nearest tenth)
Step-by-step explanation:
Area of the wooden block = area of rectangle - area of semi-circle
Area of Rectangle = length × width
Length = 9 cm
Width = 4.5 cm
Area of rectangle = 40.5 cm²
Area of semi-circle = ½(πr²)
Radius (r) = ½ of diameter = ½*5 = 2.5 cm
π = 3.14
Area of semi-circle = ½(3.14*2.5²)
Area of semi-circle = 9.8125 cm²
✅Area of the wooden block = 40.5 - 9.8125 = 30.7 cm² (nearest tenth)
The area of the wooden block is [tex]30.7 cm^2[/tex].
The calculation is as follows:We know that
Area of the wooden block = area of the rectangle - area of semi-circle
Here
[tex]Area\ of\ Rectangle = length \times width[/tex]
Here Length = 9 cm
And, Width = 4.5 cm
So,
Area of rectangle = [tex]40.5 cm^2[/tex]
Now
Area of semi-circle is
[tex]= \frac{1}{2} \pi r^2[/tex]
[tex]= \frac{1}{2} \times 3.14\times 2.5^2[/tex]
= [tex]9.8125 cm^2[/tex]
Now the Area of the wooden block is
= 40.5 - 9.8125
= 30.7
Therefore we can conclude that the area of the wooden block is [tex]30.7 cm^2[/tex].

27x9^3x can be written in the form 3^k where K is an expression in terms of x. Find k
Answer:
k = 3 + 6x
Step-by-step explanation:
Using the rule of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]
[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]
Given
27 × [tex]9^{3x}[/tex]
= 3³ × [tex](3^{2}) ^{3x}[/tex]
= 3³ × [tex]3^{6x}[/tex]
= [tex]3^{3+6x}[/tex]
= [tex]3^{k}[/tex] → with k = 3 + 6x

When the polynomial in P(x) is divided by (x - a), the remainder equals P(a).
A. True
B. False
Answer:
A
Step-by-step explanation:
The Remainder theorem states that a polynomial f(x) divided by (x + h ) has remainder given by
f(- h)
Thus if P(x) is divided by (x - a) then the remainder is P(a) → True

The given data is 64, 72, 85, 80, 72, 89.
First we arrange it in ascending order.
64,72,72,80,85,89
The middle two terms are 72 and 80.
There are 6 no of observations.
The median when n is even is given by :

AABC has vertices A(1,3), B(2,5), and C(5,3). What are the coordinates of B' after
the translation by the vector <1,4>? (Give your answer as an ordered pair without spaces.)
Answer:
The coordinates of point B' are (3, 9)
Step-by-step explanation:
If the point (x, y) translated by a vector <a, b>, then its image is (x + a, y + b)
Let us use this rule to solve the question
In Δ ABC
∵ The coordinates of vertex A are (1, 3)
∵ The coordinates of vertex B are (2, 5)
∵ The coordinates of vertex C are (5, 3)
∵ Δ ABC is translated by the vector <1, 4>
→ By using the rule above add the x-coordinate of point B by 1
and the y-coordinate of point B by 4
∴ B' = (2 + 1, 5 + 4)
∴ B' = (3, 9)
∴ The coordinates of point B' are (3, 9)
